Since I am able to sew, I immediately wondered how much it would cost me to make my own grow bag. The fabric store had Burlap on sale that weekend, so I devised a design and a plan. I would make my own 18" x 18" square grow bags.
It would take 5 yards to make 6 bags of varying heights (some for potatoes, some for carrots, and some for things like lettuce). With the fabric on sale, this would cost me $13 with taxes. + $2 for heavy duty thread that was also 50% off. So $15 for 5 bags! I am already way ahead of retail. Plus my bags will last more than one season and be breathable.
Here is what I did:
First I cut one 6' long strip to be the side walls of the bag and I cut an 18" x 18" strip to be the base of the bag.
I sewed the two ends of the long strip together and then sewed this piece to the base.
Now I have a bag. However, since its burlap, it doesn't stand up on its own.
I tried a few things to get it to stand that I didn't like.
